Maj. Gen. Munir Muniruzzaman, the chairman of the Global Military Advisory Council on climate change, said that climate change "is the greatest security threat of the 21st century,” reports the Guardian[4]. He and other military leaders are warning the world that action must be done now to combat climate change’s effects.

“We’re going to see refugee problems on an unimaginable scale, potentially above 30 million people,” said Maj. Gen. Muniruzzaman.

“Climate change could lead to a humanitarian crisis of epic proportions,” said Brig. Gen. Stephen Cheney[4], the CEO of the American Security Project and a member of the U.S. state department’s foreign affairs policy board.

Brig. Gen. Cheney continued:

“We’re already seeing migration of large numbers of people around the world because of food scarcity, water insecurity, and extreme weather, and this is set to become the new normal.”
